Detailed Description
template<typename _Engine, typename _Dist>class std::variate_generator< _Engine, _Dist >
Produces random numbers on a given distribution function using a non-uniform random number generation engine.
Todo
the engine_value_type needs to be studied more carefully.

Constructor &; Destructor Documentation
template<typename _Engine , typename _Dist > std::variate_generator< _Engine, _Dist >::variate_generator (engine_type__eng,
distribution_type__dist) [inline]
Constructs a variate generator with the uniform random number generator __eng for the random distribution __dist.
Exceptions:
Any exceptions which may thrown by the copy constructors of the _Engine or _Dist objects.
